Description

[Detailed Description of the Invention] The present invention relates to an answering machine in which response messages are stored in an IC memory.

An answering machine is a device that is attached to a telephone, and when a caller calls from another telephone, the device sends a response message to the effect that the caller is not at home and if there is any business, it is recorded. is sent to the other telephone set, and when a message is received, it is recorded on a message recording tape installed in this device. Furthermore, when this answering machine is operated, recorded messages are played back.

Conventionally, there have been methods such as recording and reproducing the plurality of response messages on a dedicated tape, or storing them in an IC memory, but the former requires a large number of mechanisms, and the latter requires a voice Since a large amount of storage capacity is required to store the data, there is a drawback that an IC memory with a large amount of storage capacity and its power failure compensation circuit are required.

The present invention overcomes the drawbacks of the prior art and provides an answering machine that only needs to store one selected response message in its IC memory.

The present invention will be explained below based on the drawings.

FIG. 1 shows a conventional answering machine equipped with a large-capacity IC memory. First, send the first response message to microphone 2. The audio signal supplied to the microphone 2 is amplified by an amplifier 31, converted into a digital signal by an analog-to-digital converter (hereinafter referred to as an A/D converter), and is stored in the first memory location of the IC memory 6. be remembered. Similarly, the second and third response messages are sent to the second and third response messages in the IC memory 6, respectively.
stored in the th memory location. In this way,
Preparation is completed by storing a plurality of response messages in the IC memory 6.

Next, the response operation of the answering machine will be explained.

The answering machine is set to a state in which it is waiting for a call signal by pressing the device button 9. When a calling signal is supplied from the telephone line 104, the control device 8 presses the operation button 9.
The number, etc. determined and memorized in advance by
Send to IC memory 6. Based on this control signal, the selected response message in the IC memory 6 is supplied to a digital-to-analog converter (hereinafter referred to as a D/A converter). This D/A converter converts the digital signal into an audio analog signal, and sends the selected response message to the caller through the reproducing amplifier 33 and the recording/reproducing switch 11. Next, the control device 8 switches the recording/reproducing switch 11, and the message from the telephone line 104 is recorded on the recording tape 1 through the recording/reproducing switch 11 and the recording amplifier 32. If you later play back the message recorded on this answering machine, you will be able to listen to the contents of calls made while you were away.

Furthermore, in the past, it was necessary to equip the IC memory 6 with a power failure compensation circuit 7 so that the memory would not be erased even in the event of a power failure.

Next, one embodiment of the present invention will be described.

FIG. 2 is a diagram showing the contents of the beginning of the business recording tape 10. FIG. 3 is a system diagram of the answering machine of the present invention.

First, a case will be described in which response messages A, B, and C (here explained as three messages) are recorded on the business recording tape 10.

When the operation button 90 of the operation unit is used to enter the response message recording state, the message recording tape 10 of the answering machine unit 102 begins to rotate, and the first response message is recorded on the message recording tape 10 under control from the control device 80. As the selection signal 100, the signal of frequency 1 which is the response message selection detection signal 105 is 1.
recorded twice. Next, a response message A is blown into the microphone 20. When the operation button 90 is further operated, the control device 80 records frequency 1 twice, and then records the response message B from the microphone 20.

Next, in a similar operation, frequency 1 is recorded three times on the business recording tape, and later, response message C is recorded. When the operation button 90 is used to terminate the response message, the control device 80
As a result, a signal of frequency 2 is recorded on the message recording tape as the message recording section cue detection signal 106. In the business recording tape 10, the part after this signal of frequency 2 becomes the business recording part.

The second is a message, with storage capacity for only one message.
The operation of storing the selected response message in the IC memory 60 will be explained.

When response message B is selected, by pressing the corresponding button of the operation buttons 90 twice, the control device 8
0, the comparison circuit 64 in the detection device 103
2 is set, and the business recording tape 10 starts rotating and playing. The signal of frequency 1, which is recorded once at the beginning of response message A, passes through the filter 62 that allows only the frequency 1 to pass, and is output to the counter 6.
3 and supplies the count value 1 to the comparator circuit 64. Here, it is compared with the set value 2, but since they do not match, a reset signal is simply sent to the counter 63. The frequency 1 or the length of the signal is selected so that the filter 62 does not pass the voice signal of the response message. Next, the signal of frequency 1 recorded twice at the beginning of response message B passes through a filter 62 and is counted by a counter 63, and the counted value 2 is supplied to a comparison circuit 64. Here, since 2 is the same as the set value, there is an output from the comparator circuit 64. The control device 80 receives this output, that is, the detection output from the detection device 103, amplifies the response message B recorded after two frequencies 1, and stores it in the IC memory 60 as a digital signal using the A/D converter 40. to control the The control device 80 then advances the business recording tape 10 to the cue detection signal section of frequency 2.

Third, a case in which a calling signal is received from a telephone line will be explained.

The control device 80 detects that a call signal has arrived at the answering machine, converts the response message B stored in the IC memory into an analog voice signal through the D/A converter, and outputs the response message B to the amplifier 36 and the recording/reproducing switch. 12 to the telephone line 104. Next, when the message is sent from the telephone line 104, the message is recorded on the message recording tape 10 through the recording/reproducing switch 12 and the amplifier 35.

Later, if the answering machine is rewound and played back up to the cue detection signal section, it is possible to listen to calls that have come in while the user is away. Further, the response message can be changed using the operation button 90 of the operation section, which is the same as the response message setting described above.

Next, a case will be described in which a remote controller is used to listen to a message recorded on an answering machine.

When a telephone line is connected by a call from an outside telephone of a person who is out of the house, the telephone answering machine sends out a response message. When the answering message has been sent and the message is being recorded, if the person who is away sends a remote control signal for listening from a remote controller (not shown) via the telephone line, the answering machine is controlled. The device 80 detects the signal, rewinds the business recording tape 10 in the answering machine section 102, and plays it back from the cue detection signal section.

Therefore, the person who is out of the house can know the contents of the phone call received while the person is away.

Next, a case will be described in which a remote controller is used as the operation unit of the answering machine and a person who is out of the house instructs to change the response message from the telephone.

When a telephone line is connected by dialing from an outside telephone by a person who is out of the house, an answering machine sends out a response message. When the answering message has been sent and the message is being recorded, when the person who is away sends a remote control signal from the remote controller via the telephone line to instruct the answering message, the control device 80 of the answering machine The signal is detected, the message recording tape 10 in the answering machine section 102 is rewound, and the signal of frequency 1, which is the response message selection detection signal at the beginning of the response message A, is played back. Here, the recording/reproducing switch 12 is switched to the reproduction side by the control device 80.

When changing from response message B to response message C, part of the signal from the remote controller is such that the controller 80 sets the comparator circuit 64 to a value of 3. This is because the response message selection detection signal with frequency 1 is at the beginning of response message C.
Because it has been recorded twice. The subsequent operation is the same as when operating the operation button 90 described above. At this time, each response message selection detection signal and each response message are sent to the telephone set outside the home via the telephone line, so it can be confirmed that the remote control for selecting response message C has been performed.

The operation after a power outage will be explained next.

When the power outage is restored, the control device 80 detects that power supply has started, and sets a signal 1 in the comparison circuit 64 to automatically select response message A, and also sends the message recording tape 10 in the answering machine section 102.
Rewind and start playing. Since the frequency of the response message selection detection signal 1 at the beginning of the response message A is detected by the detection device 103, the control device 8
0 causes the response message A to be stored in the IC memory 60. Therefore, since the response message A is always sent to the telephone line 104 after the power is restored, the response message A may be filled with a general message indicating that the user is not at home.

In the above explanation, we explained three response messages, but if we increase the number of response messages,
Able to provide detailed responses.

As explained above, the answering machine of the present invention does not require an IC memory power failure compensation circuit, and
Moreover, the IC memory may have a small capacity. Also,
Compared to directly speaking a response message into the memory IC during remote control, etc., the mechanism is simpler and there are fewer failures.
